Heat the grill to medium-high. Heat the oil in a small non-stick, ovenproof frying pan and fry the bacon for 5 minutes until crisp. Add the garlic and chilli, and cook for 2 minutes, then tip in the spinach mixture. Cook gently for a minute until the bottom is set, then sprinkle the red peppers over the top. Cook for another few minutes until the bottom is lightly golden. Sprinkle with the cheddar and put under the grill for 2-3 minutes until cooked through and golden on top. Cut into wedges and serve with the dressed rocket.
